An approach to integrated guidance/autopilot design for missiles based on terminal sliding mode control

An approach to integrated guidance/autopilot design for missiles on the sea is proposed in this paper. When the integrated guidance/autopilot model of the yaw plane is formulated, the guidance/control law is designed based on the backstepping idea and terminal sliding mode control theory. For the unavailable information of the maneuvering target, an estimating method is given, and an auxiliary control based on a sliding mode estimator is used to offset the estimation error. Finally, to verify the effectiveness and tightness of the integrated design scheme, the simulation of some anti-vessel missile against high maneuvering targets have been made, the simulation results have shown that high accuracy of hitting target can be obtained.
